They provided a pillow and blanket which was very nice, and the crew were helpful in finding space for items during take-off and landing. The boarding and exiting were fairly quick.

Everything on board costs extra, including basic drinks and snacks, but that's to be expected on cheaper flights. I assumed that the inflight movies cost money as well, although I didn't watch any because I didn't have headphones.

My flight was delayed by almost 6 hours. For days I received alerts about it being my last chance to upgrade my flights. Many hours before my flight they knew the flights were delayed yet I did not receive one text or e-mail to let me know. I was at the airport for 9 hours. 9. Worst part is that I'm not even the only one.

There was one particularly pretty crew member with a great laugh and she was very friendly

I flew out with the same luggage that I flew in with. They charged me $56 for it.
It seemed as if they made a new rule out of the blue and included my personal bag my carry on. It wasn't that they had to be concerned about the FAA weight requirements because the flight was only about 80% full.
The in-flight entertainment was limited and there was no audio... so in other words, you could not simply turn on music to go to sleep by.
This is a very bare-bones airline.
Also, one flight attendant was perhaps the rudest person I've ever come across. "Go talk to someone else - I'm busy." All I asked for was a fork. She was simply opening a bin at the moment.

I think this airline has an attention to detail and level of service which surpasses most other airlines. Whilst remaining competitive these factors make traveling with Finnair a far more comfortable and attractive proposition for me. In addition, Helsinki airport must be one of the best around.

The flight did eventually take off, unlike a few others leaving around the same time.

We were delayed several hours and were never told why. Mostly there were no Aeroflot staff at the gate to ask. When there was, they said they couldn't help us because our flight was a codeshare with FinnAir. At the last minute they switched gates, sending us all scurrying.

Attendant at gate insisted my daughter's carry-on bag get checked because he put it crooked into the sizer. When I adjusted it and showed him that it fit, he still insisted that we check it. Unpleasant way to start our trip.

The crew was nice

I flew American four times in 7 days, every flight was delayed. delay times varied from 90 minutes to over three hours. Fog in Chicago was beyond anybody's control, but the other times were not weather related, I recently flew frontier Air and their flights were also late. I jinxed myself by stating I never have this issue with AA. Great job at proving me wrong. I flew a good bit last year and these issues didn't start until after the new year., Thank you for your time.

None of the experience was pleasant

First flight was delayed causing us to miss the 2nd flight and we ended sleeping on a chair at the airport waiting for a morning flight. AMERICAN AIRLINES didn't even have the decency to put us in a hotel for the night due to their delay. Then they added a 2nd lay over which was delayed for hours also. Traveling was to visit my mother who had cancer and I was sick so this made the trip even more distasteful.

The food was ok. Movie selection was decent and the screens are a lot better than on jet airways.

Boarding was a little delayed. Service was a little slow, but the crew was courteous and did their best.

The flight from Toronto to Boston is extremely short, about an hour. I don’t feel as though I can rate the food since I didn’t buy any, it just doesn’t give me an option to not rate it. It was a completely full flight. It was as comfortable as can be. It’s a smaller plane so you feel everything but the captains were good flyers.

I’m not sure if this is something I can really complain about but I wish the flight attendants would’ve spoken a bit lower. For a plane where half of the people there had missed their connecting flight and were put on a 6:30 am flight, I don’t think we wanted to hear about their detailed personal lives.

Around $700 air fair for round trip flight to Asia is a good deal.

The flights between Vancouver and Dallas are small and tight, very uncomfortable. Normal carry on csn not fit into overhead bins.

When two passengers got into a brawl over who knows what, it took two hours for the police to come on board and take them off the flight.
They should have been removed quickly.
Missed connecting flight.

We had to walk from gate z all the way to gate B carrying all the bags which was painful, the plane was very tight and old that I had to put all my carry on bags in the floor. I personally had to help the crew members to pick up the food trays because they were very limited and no entertainment at all which was really boring.

Beside for the music and movies, you should give us the possibility to make a search and find what we want to watch or listen

I'm very disappointed because i wasn't allowed to travel back to the US from Brussels (Belgium). i was supposed to connect in Toronto but because I'm a foreign student in the US, I wasn't aware that i needed a Canadian Visa to transit in Toronto. so lost my flight and i hard to spend another thousand euros to catch the next flight that will connect in the US territory. I made all the call possible to resolve my flight issue and no one could help me either Brussels airline personnel or the kayak customer service. until today i didnt have not even a email to let me know what happen.

What you expect from an internal US flight: no food, crowded flight, cramped seats. I have come to expect two things - arrive on time and arrive safely. The good, we arrived safely.

Pulled away from gate and sat on tarmac for over an hour while technical difficulties fixed. We should not have boarded until plane was ready. We arrived over one hour late and just made connecting flight. Our luggage was not so fortunate.

Every flight (to and from India) seems to have the chicken option run out. Why not order accordingly?
Had a bad seating experience. LH.com showed that I had completed the boarding process. But when I went to the counter, my seat was changed without my consent (to a worse seat), and I was told that the online process wasn't complete!! Then the website should say accordingly. It's really annoying when this happens. I think the ground crew in New Delhi duped me.
At one point, my call button for my meal was ignored for ~30 minutes on the plane. And then I was told there was no more chicken, and handed a veggie wrap. One wonders whether I could have gotten chicken 30 minutes ago!
